Case Report. Isolated carotid artery originating from the pulmonary trunk is an exceedingly rare anomalous origin of head and neck vessels. We present this finding, along with a persistent embryonic trigeminal artery, in a male infant with multiple cardiac defects and other congenital anomalies associated with CHARGE syndrome. After extensive investigations, cardiac catheterization revealed the...

A prospective, randomized trial on 416 consecutive cases of appendicectomies was carried out in which half of the cases had simple ligation of the stump and the rest had invagination of the stump in addition. The two groups were matched for age, sex, state of personal hygiene and nutrition. The incidence of wound infection, and early and late post-operative complications remained comparabl...

Ligation of both ureters in the dog results, as has been reported briefly in an earlier communication," in extensive systemic lesions similar in every respect to those that follow the ligation of both main renal arteries. Ureteral ligation thus provides an opportunity not available in the latter circumstances for studying the effects of the necrotizing substance on the kidneys themselves. In th...

PURPOSE Characterization of the structural changes occurring in the pulmonary arteries resulting from surgically produced congenital diaphragmatic hernia in rabbits, with particular emphasis on the preventive effects of prenatal tracheal ligation or administration of intra-amniotic dexamethasone or surfactant. METHODS Twenty rabbit fetuses underwent surgical creation of a left-sided congenita...

During the years 1 9 9 2 1 9 9 6 11 cases of arteriovenous fistula or aneurysm were reported in the Department of Surgery at Tikur Anbessa Hospital (TAH). Ten of these cases will be presented. Eight of the cases were operated upon in 1996. The mean age of the patients was 32 years (range 17-49). Nine were men. The aneurysms were located in the lower extremities in eight patients, and in the upp...

OBJECTIVE Chronic arterial occlusion results in arteriogenesis of collateral blood vessels. This process has been shown to be dependent on the recruitment of growth-promoting macrophages to remodeling collaterals. However, the potential role of venules in monocyte recruitment during microvascular arteriogenesis is not well demonstrated. First, we aim to document that arteriogenesis occurs in th...

UNLABELLED Limb ischaemia caused by formation of dialysis fistula is rare but serious complication. The severity of symptoms may vary but rest pains and necrotic lesions are observed in most advance cases. In these patients different invasive procedures for treatment are performed - from simplest dialysis fistula ligation to complicated vascular reconstructions. The aim of the study was to eval...

â  background treatment of hemorrhoid disease is one of the most challenging fields in general surgery in which different methods are used to treat this condition. in this study, we compared the manometric and clinical results of three treatment methods for hemorrhoids. me t hod s a total of 150 patients with symptomatic grades ii or iii internal hemorrhoids were randomly assigned to three grou...

background: the present study was conducted in order to evaluate the effects of bilateral uterine artery ligation (bual) on the ovarian follicular fate, and alterations in carbohydrate, lipid, lipase and serum levels of f9sh, lh, prolactin, estrogen and progesterone. methods: twenty-four mature female rabbits divided into two test and control-sham groups. the animals underwent ovariohystrectomy...

objective(s): electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. the leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. the aim of this study is to research the effect of atp-dependent potassium (katp) channel blocker (gl...
